  9. 9. • The largest wind turbine in the world, located in Hawaii, stands 20 stories tall and has blades the length of a football field. • An average wind speed of 14 miles per hour is needed to convert wind energy into electricity. • The first power-generating turbine was constructed in Ohio during the late 1800's and was used to charge batteries. • Wind energy is the fastest growing segment of all renewable energy sources. 30-12-2013 9

  15. 15. It is considered 'renewable energy' because... • The technology used to convert the sun's power into electricity does not produce smoke (carbon dioxide and other air pollutants). • Tapping the sun's energy does not usually destroy the environment. 30-12-2013 15
  16. 16. 30-12-2013 16 Largest solar thermal power plant generating facility in the world: Solar Energy Generating Systems (SEGS) in California, with the combined capacity from three separate locations at 354 megawatts.
  17. 17. •Solar energy will last forever whereas it is estimated that the world’s oil reserves will last for 30 to 40 years. 30-12-2013 17
  18. 18. •Solar cells make absolutely no noise at all. On the other hand, the giant machines utilized for pumping oil are extremely noisy and therefore very impractical. 30-12-2013 18
  19. 19. •Very little maintenance is needed to keep solar cells running. There are no moving parts in a solar cell which makes it impossible to really damage them. 30-12-2013 19
  20. 20. •Solar energy can be used in remote areas where it is too expensive to extend the electricity power grid. 30-12-2013 20
  21. 21. •Solar energy does not cause pollution. However, solar collectors and other associated equipment / machines are manufactured in factories that in turn cause some pollution 30-12-2013 21
  22. 22. • Biomass is used to make biofuels. • Biomass is biological material derived from living, or recently living organisms. • Biofuels are liquid fuels which have been derived from other materials such as waste plant and animal matter. 30-12-2013 22
  23. 23.  Waste residues will always exist – in terms of scrap wood, mill residuals and forest resources.  Properly managed forests will always have more trees, and we will always have crops and the residual biological matter from those crops. 30-12-2013 23

  27. 27. •Hydropower is renewable energy source that doesn't cause global warming because it doesn't releases dangerous greenhouse gases. •China is the largest producer of hydroelectricity, followed by Canada, Brazil, and the United States (Source: Energy Information Administration). •Hydropower is the most important and widely-used renewable source of energy. 30-12-2013 27

  30. 30.  To meet any changes in demand for electricity, hydroelectricity generators can be stopped and started in minutes.  A fossil fuel power station can take up to eight hours to shut down or restart  A nuclear power station can take up to several days. 30-12-2013 30
  31. 31.  Operation and maintenance costs for hydroelectricity plants are much lower than for thermal electricity power plants.  Breakdowns are few because their mechanical design is relatively simple, and no excess heat is generated during operations. 30-12-2013 31
  32. 32. Constant rate of electricity production Long life No waste by- products 30-12-2013 32
  33. 33.  Geothermal energy is the heat from the Earth.  Geothermal energy is called a renewable energy source because the water is replenished by rainfall, and the heat is continuously produced by the earth. 30-12-2013 33
  34. 34. The Pohutu Geyser in New Zealand erupts with a natural blast of the Earth's interior heat. 30-12-2013 34
  35. 35. • Because geothermal energy is energy in and of itself, no outside sources of fuel are needed to keep the power houses running. • The supply of this renewable energy is constant, as well as without limits since the earth is never going to stop producing heat energy and in theory, energy is abundant enough to supply all the needs of all mankind. 30-12-2013 35
  36. 36.  First country in the world to set up a ministry of non conventional resources, in early 1980s  The renewable power installed capacity forms 12% of the total installed capacity as on Oct 2012  Actual electricity generation from renewable energy sources equals 49.04 billion units. 30-12-2013 36
  37. 37.  RE generation from Small Hydro power is 3421 MW, i.e 13% of RE  With 17,875 MW of generation, wind continues to account for 70% of the installed RE capacity 30-12-2013 37
